That's cobblers so feel free to shoot me down for what I am about to say even though the statistics seem to support it. The UK has a poorer education system than many civilised countries and certainly a lower standard than Germany does. That might be an indicator that they possibly are more intelligent than we are. Was that always so? Possibly but I doubt it. IMO, the UK has gone backward over the years whereas the Germans have had to learn some very hard lessons in the 20th century and with the aid of the West in rebuilding it. It has rehabilitated itself during a prolonged period of economic prosperity achieved because it had to while UK politicians have bleated on about past glories. The breeding grounds for fascism are poverty, a poor education system and the nationalist rhetoric of a demagogue. You can tick the first two in the UK.
As for the UK rejecting fascism? By making deals with them.? That is what would have happened had Churchill not been around. Stop the self -delusion and open your eyes
It is true that having been responsible for the death of tens of millions of people during WW2, Germany had to reinvent itself. I'm a big admirer of how they went about it. But the fact is, their population in the late 1920's and 1930's must take some responsibility for those deaths since they voted in Hitler. He was not imposed on them. They chose him.
Britain did sit back on its laurels after the war, and the 1970's were dire industrially. Thatcher came in and changed it. Suddenly people were working and had a much higher standard of living. Some were left behind, it's true, and that's the main criticism of Thatcher. But Blair is on record as saying he was grateful of Thatcher's legacy.
The Far Eastern countries come out best in terms of education, although it's still true that some of the best universities are still in the UK. I can't speak for Yorkshire, but around here in Sussex, the state education is good, and I haven't noticed the rise of fascism either, although the rise of the AfD in Germany is worrying given that country's past.
We have a sophisticated electorate that can compare to any other country. Germany has changed and, sure, can now compare with us. Their electorate have shown themselves to be right minded members of society, although there is still darkness in East Germany.
As for rejecting fascism in the 1930's, you have only to look at the demise of Mosley's BUF to see that the British rejected fascism. You have a warped understanding of history. What Chamberlain, Halifax and others were espousing in 1939 was not the adoption of fascism, but simply to stay out of a war in the East to save British lives. Churchill had the perspicacity to see beyond that.
